Method and Device in Ue and Base Station for Wireless Communication

11. The UE according to claim 9, wherein the first transceiver detects K1 first-type reference signal(s) in the M1 first-type subband(s); and a detection(s) for the K1 first-type reference signal(s) is(are) used for determining the K1 candidate subband(s).

12. The UE according to claim 9, wherein the first transceiver second operates a second radio signal in a second time-frequency resource according to a configuration of a second information group; the second information group is one of the Q1 first-type information groups; the first time-frequency resource and the second time-frequency resource are orthogonal in time domain; a frequency domain position of the second time-frequency resource is used for determining the second information group from the Q1 first-type information groups; only when the first information group and the second information group are one same first-type information group among the Q1 first-type information groups, the first radio signal and the second radio signal are considered to be related; and the second operate is transmit, or the second operate is receive.

15. The base station according to claim 13, wherein the second transceiver performs M1 energy detection(s) for the M1 first-type subband(s) respectively; the second transceiver transmits K1 first-type reference signal(s) in the K1 candidate subband(s) respectively; the M1 energy detection(s) is(are) used for determining that the K1 candidate subband(s) is(are) not occupied, and a detection(s) for the K1 first-type reference signal(s) is(are) used for determining the K1 candidate subband(s).

16. The base station according to claim 13, wherein the second transceiver second processes a second radio signal in a second time-frequency resource according to a configuration of a second information group; the second information group is one of the Q1 first-type information groups; the first time-frequency resource and the second time-frequency resource are orthogonal in time domain; a frequency domain position of the second time-frequency resource is used for determining the second information group from the Q1 first-type information groups; only when the first information group and the second information group are one same first-type information group among the Q1 first-type information groups, the first radio signal and the second radio signal are considered to be related; and the second process is receive, or the second process is transmit.
